Fusion 9 Studio crashes on rendering larger mp4

Hello there,

I´ve noticed that Fusion crashes every time I try to render mp4 video H.264 larger than FullHD.
Can anybody confirm this? Fusion 8 does it without problems.

I can render H.264 in UHD into a .mov just fine. But Fusion is not the fastest nor most flexible software for doing that, I'd rather output a good archival/mezzanine codec and use specialized software.

Did you try to integrate ffmpeg and use that?

Thanks for you reply..but does it crash when you try an mp4? That was my initial question. Would be very bad to switch application/encoder for that purpose. I don´t care about rendertime so much in this case.
Thanks !

Where did you find mp4? Screenshot?
